WATER-COIIOHLED VA'LVE.

SPECIFICATION formingpart of -1'.|etters Patent No.- 723,582, dated March 24, 1903.

Application filed July so, 1902.

Be it known that I, CLARENCE P. BYRNES, of Pittsburg, Allegheny county, Pennsylva nia, have invented anew and useful Water- Cooled Valve, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a sectional side elevation showing a two-flue regenerative valve system arranged in accordance with my invention. Fig. 2 is a sectional end elevation. showing two of the valves arranged side by side. Fig. 3 is a top plan view of Fig. 2. Fig. 4 is a view similar to Fig. 1, showing a modified form. Fig. 5 is a longitudinal vertical section showing the valve system as applied to athreeflue regenerative system. Fig. 6 is a partial sectional detail showing a modification of the water-cooled box. Fig. 7 is a longitudinal section showing another form of the threetion showing another form of valve for the two-flue system. Fig. 9 is a longitudinal section showing a further two-flue'form. Fig. 10 is a horizontal cross-section of the valve of Fig. 5, and Fig. 11 is a similar section showing the valve of Fig. 7.

My invention relates to the class of watercooled valves, and more particularly to the reversing-valves employed in connection with regenerative furnaces, though it may be used for other purposes; and its object is to obtain a simple and cheap construction which will belong lived and in which the parts are prevented from warping and burning out by an efficient water-cooling system for those metal parts which are subject to the action of heated gases. l

In the drawings, referring to the form of Figs. 1, 2, and 3, 2 represents a stack-flue, and 3 the flue leading to a gas-regenerator. 4t is a shallow water tan k or trough, which is placed over these lines and is provided with'flangcd ports 5 and 6, extending upwardly'through it to a level above the normal water-level therein. This tank is provided with an inlet-pipe 7 and an overflow-pipe 8 at opposite ends to maintain a circulation of cooling fluid therein. Within the tank 4 is set a water-jacketed hollow box or tank 9, having hollow side and 'tions resting on the tank-bottom.

Serial No. 117,616. (No model.)

I end walls, as shown,with closed bottoms forming legs 10, which rest within the tank. The ,box is shown as supported by bottom projec- This box entirely surrounds the ports 5 and 6, and water is maintained in the box at such a level as to cover its inner top 11. This water may 'be supplied through a perforated pipe 12, extending around the box in the lower portion of its jacketed sides, and supplied from a pipe 13, and the box is provided with a suitable overtlow 14 to maintain a constant waterlevel therein. The box in its top is provided with a flanged port 15, extending above the water-level and opening into a gas-box 16. This gas-box rests upon the top 11 of box 9 and has lower perforations 17 below the water-level to allow the water in the box to rest around the flanged port 15. Gas is supplied to this box through a suitable pipe 18,

and its flow through the port is controlled by a water-cooled valve consisting of a water-containing bucket 19, which is recessed npwardly in the central portion to provide a depending hollow water-cooled ring portion 20. This valve may be raised and lowered by a hollow stem 21, which extends upwardly through suitable metallic packing 22 in the top of the gas-box and is connected with a water-supply pipe 23. The stem is perforated in its lower portion to supply water to the water cooled valve, the water overflowing through a suitable spout 24 into the water in the cover-box. The port 6 is controlled by a valve 25, similar to the valve 19 and having a hollow stem 26, which extends upwardly through a circular flange or collar 27, projecting upwardly from the top 11. 28 is the Water-supply for this stem, the flexible pipes 23 and 28 leading from a water-supply .pipe 29, having suitable control-valve 30.

The stem 26 is preferably provided with a depending hell or ring 31 in its upper. portion, which when the valve is seated will enter the water over the cover 11 and seal the stem. The valves 19 and 25 may be operated in any suitable manner; but I prefer to provide connections which are arranged so that the port 6 will be unsealed and opened after the valve 19 has sealed the port 15, thus cutting otf the gas before the stack-flue is opened, and so ISO that on the reverse movement the stack-flue will be closed before the gas-valve is opened and that after the stack-valve is closed the gas-valve may belifted to any desired amount to regulate the entering volume of gas. I have shown for this purpose a drum 32, having flexible connections 33 and 34 with the valve-stems. These flexible connections are so arranged that in the counter-clockwise movement of the drum the stack-valve will be lowered to its'seat before the gas-valve is unsealed,and afurther movement of the drum then slacks away on the cord 34, the cord 33 lifting the gas-valve to any desired amount. This movement may be obtained by a leverhandle 35, having a spring-catch 36 entering recesses in asegment-plate 37. It will be understood that the valves may be moved by any desirable connections, that a separate regulating-valve may be used in the gas-flue, and that the valves 19 and 25 may be connected to a two-armed lever, so that one will couns tel-balance the other in their movements. The air-regenerator valves may be arranged in the same manner as that shown, except that the gas-box is not used, and a plain cover-valve may be used to control the air entering the port through the cover ll. The two gas-valves for the furnace may be connected so as to counterweight each other, and the sack-valves maybe similarly connected and counterbalanced.

Instead of placing the gas-valve 19 above the cover 11 a gas-valve may be used within the box. Thus in Fig. 4 I show a form similar to that of Fig. 1, except that the gas'valve 19 consists of a shallow bucket or tank within the water-cooled box, which is arranged to be sealed in its upper position by a depending water-cooled annular leg or ring 38 in the cover 11. The gas-box 1G in this case becomes a vertical flue,which leads downwardly and forms an inner extension of the Watersealing ring 38. In this case the cover portion 11 will be su-fiiciently elevated above the ports to allow the gas to enter the box when the valve 19 is lowered and to flow around the valve and downwardly into the port 3.

The system may be applied to the ordinary three-flue regenerative valve system where two regenerator-flues are placed on either side of a stacleflue. Thus in Fig. 5 I show an intermediate stack-flue 2, with gas-regen erator flues 3 on either side thereof. In this form 5 are the gas-ports, leading upwardly through the water-cooled box 4, and 6 is the stack-port. In this form each valve consists of a hollow cylindrical water-jacketed casing 39, having an offset portion 40 of annular form at the bottom which rests upon the gas-port and seals it by means of the dependingwater-cooled portion. The jacketed cylinder extends upwardly through the cover 41 of the inciosing water-jacketed box 42 and extends into a gas'chamber 43, provided on the top of the box 42. Each of the valves extends upwardly within an annular flange resfss 44, which extends above the water-level over the cover 41, and a depending sealing-ring 45 is provided which enters the open hollow annular chamber of the valve to seal its upper end when the valve is raised. When the valve is lowered, an annular depending bell or ring 46 enters the water over the cover4l and seals the gas-chamber from the lower chamber. The stem 47 of each valve is a hollow water-conducting tube connected by branch tubular supports 47 with the annular jacket of the valve. Water is thus supplied to each valve and overflows at its top through a spout 48 into the water in the cooled coverbox. The gas enters the upper box through the port marked 49. The valves in this form will be operated in the ordinary way, one being raised as the other is lowered. In the position shown gas enters through the lefthand valve and passes down through the valve into the gas-regenerator. At the same time the waste gases rise through the righthand port and pass to the stack-flue 2. In this case again I prefer to so arrange the valve connections that the valve being lowered will be sealed at its lower end before its upper end is unsealed to admit the gas. This may be done by suitably proportioning the depth of the sealing-ring 45 to that of the depending leg 40 of the valve.

In the above forms the gases are allowed to contact with the water in the lower tank. If it is desired to reduce the surface of water exposed to gases, the jacketed box 9 may be provided with a double bottom having circular holes arranged to extend around the ports 5 and 6, one or both of these holes being large enough to admit the valve 25 to the water seal or trough. Thus in Fig. 6 I show the box 9 as having a double bottom 50, connecting with the sides and having holes for the ports 5 and 6, one of these holes being large enough to allow the valve 25 to pass down through it into the water in the tank 4.

In Fig. 7 I show another form of valve system applied to a three-port arrangement. 'In this case the water'jacketed box 4? is provided with a partition 51, which is hollow and connects with the top and sides of the box to allow the water to circulate within it. This partition extends down into the water in the tank 4" and is provided with an intermediate horizontally-extending portion containing a hole through which the single valve 52 slides vertically. This valve is of the same general form as that of Fig. 5, and its depending upper flange 46 enters an open annular watertrough 53 when the valve is in its lowered position, as shown. The trough 53 sets upon the horizontal portion of the partition around the hole of the valve. The top 41 of the box is provided with a depending annular sealing-flange 45, which prevents gases passing through the valve when it is lifted.-

I have shown the gas-box as provided with two ports 54, leading down into the box through its upper cover, each of these ports being controlled by a water-cooled valve 25 of a form similar to that shown in Fig. 1. When the valve is in the position shown, the central stack-flue 2 is connected with the left-hand port 3 through the cylindrical valve, and the gases from the regenerator thus pass to the stack, while the entering gas passes down through the right-hand port 54: and the right-hand flue 2 through the other regenerator. When the valve is lifted to its upper position, the gas-valves are shifted to close the right-hand port and open the lefthand port 54, and the waste gases from the right-hand port 3 then flow directly through the casing to the central flue 2 In Fig. 8 I show a form similar to that of Fig. 2, except that the body portion of the valve 25 is not open-topped, the sides of the depending sealing-flanges being continued upwardly to form an outer valvestem 55, which extends up through the inner top 11 of the box. The central supply-stem 26 is used as before and may be provided with lower branch pipes 56, which lead out into the hollow lips to insure circulation therein. In this case the upper sealingbell 27 is formed on the outer valve-stem 55, and the water in the hollow valve flows over this flange into the water covering the top of the box instead of into the lower tank.

In Fig. 9 I show a two-flue form, wherein the stack-flue 2 extends vertically Within the lower part of the watercooled box 9, while the regenerative flue 3 extends through a hole in the side of this box. In this case I have shown the tank 4. as being in the form of an annular trough surrounding the stackflue, while the Water-cooled box 19 has a closed annular bottom and fits neatly around the annular trough 4. The open-topped water-cooled valve 25 is sealed in its lower position in the tank 4, in which case the-gas entering through the flue 18 flows through the box and the flue 3 to the regenerator. The box is provided with a depending annular water-leg 38, which enters the annular leg of the valve when it is lifted, thus preventing gas from entering the box while the gases from the regenerator rise through the flue 3 and descend to the stack through the flue 2.

In the form of Figs. 5 and 7 the overflowpipe 57 for the top of the water-cooled box may be sealed off from the gases by a flange or pocket 58.

The advantages of my invention result from the simplicity of the system and the complete system of water-cooling the valve and easing. Warping or cracking of the metal is avoided and leakage prevented. The system also provides for the regulating of the gas or air and for the closing of the stack valve or valves before the gas-valve is opened. The valves may be easily counterbalanced by connections to a lever or drum system or to separate counterweights, thus making them easy to operate.

The valve may be employed for other purposes than in connection with regenerative furnaces, and the construction may be varied widely, both as to the form of the valve proper, its casing, the water-cooling system and connections, and the mechanism for operating the valve or valves,without departing from my invention.
